Poland’s Foreign Minister Radoslaw Sikorski (C), German counterpart Frank-Walter Steinmeier (L), Ukraine’s opposition leaders Vitaly Klitschko (2nd L) and Arseny Yatsenyuk (2nd R) prepare to leave after signing an EU-mediated peace deal with President Viktor Yanukovich, aiming to end a violent standoff that has left dozens dead and opening the way for a early presidential election this year, at the presidential headquarters in Kiev February 21, 2014. Russian-backed Yanukovich – under pressure to quit from the mass demonstrations in Kiev – earlier offered a series of concessions to his pro-European opponents, including a national unity government and constitutional change to reduce his powers, as well as the presidential vote.
